201

Type 201 stainless steel is an alloy that contains half the nickel and more manganese and nitrogen than other popular steels. While it is less expensive than some other alloys (because of its low nickel content), it is not as easy to work or form. Type 201 is an austenitic metal because it is non-magnetic stainless steel that contains high levels of chromium and nickel and low levels of carbon.
